. What would happen to a person in space, outside of a space ship with no space suit?

.The person would very soon die, either from lack of oxygen or more likely from the extreme cold in the icy near-vacuum of outer space; it would be like being flash-frozen on earth. After that, the body would be freeze-dried, scientists theorize. The water in the body would freeze and eventually dissipate into space, leaving behind the other body constituents. Ice can evaporate without going through the liquid phase, a process called sublimation. It happens with refrigerator ice all the time.

Because there is no oxygen, there would be no decomposition of the body, and there is little evidence that there would be degradation by microbes in space. It would be like storing meat in the deep freeze; it would eventually dry up, but how long it would take nobody really knows. The process would be similar but much slower if the person died in a spacesuit.
